[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 6 The figure shows the first embodiment of the modular distribution network switch cabinet structure of the present invention.

[0023] The modular distribution network switch cabinet structure in this embodiment includes: multiple groups of switch cabinet bodies, any group of switch cabinet bodies includes: a cable cabinet 1, a first assembly cabinet 2 installed on the cable cabinet 1, and a second assembly cabinet 3 installed on the first assembly cabinet 2; a bottom-mounted diversion pump 4 installed on the outer side of the bottom of the cable cabinet 1; multiple top-mounted diversion pumps 5, the multiple top-mounted diversion pumps 5 are installed one by one on one side of the inner top surface of the cable cabinet 1, one side of the first assembly cabinet 2, and one side of the inner top surface of the second assembly cabinet 3; multiple heat exchange components 7, the multiple heat exchange components 7 are installed one by one on the inner top surface corners of the cable cabinet 1, the inner top surface corners of the first assembly cabinet 2, and the inner top surface corners of the second assembly cabinet 3, and the bottom-mounted diversion pump 4, the multiple top diversion pumps 5 and the multiple heat exchange components 7 are connected one by one.

[0024] Wherein: by switching the air and liquid cooling structures of the heat exchange component 7, and / or respectively controlling the working states of the bottom diversion pump 4 and multiple top diversion pumps 5, the interior of each cabinet is diverted and cooled individually or simultaneously.

[0025] In the specific implementation, the switch cabinet bodies in this embodiment are set to three groups, and the structure of each group of switch cabinet bodies is the same, which is a combination of a cable cabinet 1, a first assembly cabinet 2 and a second assembly cabinet 3. The three groups of switch cabinet bodies are assembled and connected horizontally. The following takes the structure of one group of switch cabinet bodies as an example to explain how each cabinet performs heat dissipation.

[0026] Each cable cabinet 1, the first assembly cabinet 2 and the second assembly cabinet 3 is equipped with a heat exchange component 7, and the heat exchange component 7 is a heat dissipation structure that can be switched between air cooling and liquid cooling; each cable cabinet 1, the first assembly cabinet 2 and the second assembly cabinet 3 is equipped with a top diversion pump 5, and the top diversion pump 5 and the heat exchange component 7 in each cabinet are connected to the same bottom diversion pump 4 on the outside of the bottom of the cable cabinet 1 through pipelines.

[0027] Among them: the heat exchange component 7 is a heat dissipation structure that can be switched between air and liquid cooling means that the heat exchange component 7 has an independent liquid cooling heat dissipation structure and can be connected to the liquid cooling heat dissipation pipeline composed of the bottom diversion pump 4 and the top diversion pump 5. The bottom diversion pump 4 can receive control instructions to perform independent air cooling and heat dissipation on each cabinet, and can also be connected to the top diversion pump 5 to drive the heat exchange liquid inside the heat exchange component 7 to circulate through the top diversion pump 5 to enhance the heat exchange effect.

[0028] Preferably, the top of the three sets of switch cabinet bodies is provided with a top heat exchange groove 8, and the inner bottom surface of the top heat exchange groove 8 is respectively provided with a heat dissipation hood 9 and a heat dissipation liquid pipe 10 connected to the heat exchange assembly 7. During implementation, the heat dissipation hood 9 is an arc-shaped structure with an upper opening, and the heat dissipation liquid pipe 10 is arranged at the upper opening of the heat dissipation hood 9, which can prevent the top dust from falling into the heat dissipation hood 9 and improve the heat exchange and heat dissipation effect.

[0029] Furthermore, the bottom-mounted guide pump 4 is installed on the outside of the bottom of the cable cabinet 1, and its function is to realize bottom air extraction, which is the power source for air-cooling heat dissipation. In addition, it can also be linked with the top-mounted guide pump 5. When air is introduced into the heat exchange component 7 through the top-mounted guide pump 5, the hot air absorbs heat from the heat exchange liquid in the liquid guide channel on the upper layer of the heat exchange component 7, thereby enhancing the heat dissipation effect.

[0030] Through the structure in which the bottom diversion pump 4, multiple top diversion pumps 5 and multiple heat exchange components 7 are connected in a one-to-one correspondence, a single drive unit of the bottom diversion pump 4 can be used to control the heat dissipation mechanism at all positions, which greatly reduces the cost and heat dissipation. The transmission mode of the multiple top diversion pumps 5 can be adjusted as needed, which greatly improves the applicability of its installation position. At the same time, since it is installed in the internal corner position, the space utilization rate is further improved.

[0031] The bottom-mounted guide pump 4 includes: a first driving housing 41, a centrifugal driving blade 42 movably installed inside the first driving housing 41, a driving motor 43 fixedly installed inside the first driving housing 41, and a first magnetically controlled linkage member 44 and a second magnetically controlled linkage member 45 axially sleeved on the driving shafts on both sides of the driving motor 43.

[0032] During implementation, the first drive housing 41 is fixed to the rear side of the bottom surface of the cable cabinet 1, and the first magnetic control linkage 44 drives and connects the centrifugal drive blade 42 and the drive motor 43. The second magnetic control linkage 45 drives and connects the drive motor 43 and the gear transmission group.

[0033] Furthermore, the overhead diversion pump 5 includes: a second driving housing 51, a temperature control sensor 52 installed at the bottom of the second driving housing 51, a centrifugal wind blade 53 installed inside the second driving housing 51, and a third magnetically controlled linkage member 54 and a gear transmission group that are movably installed inside the second driving housing 51.

[0034] The function of the gear transmission group is to realize the transmission between the bottom diversion pump 4 and the top diversion pump 5. During the implementation, the driving motor 43 controls the centrifugal wind blades 53 to rotate through the second magnetic control linkage 45, the gear transmission group and the third magnetic control linkage 54, so that air is drawn in through the opening at the lower end of the heat exchange component 7, and the air is guided upward into the heat dissipation hood 9 for discharge.

[0035] During implementation, the first magnetically controlled linkage part 44, the second magnetically controlled linkage part 45 and the third magnetically controlled linkage part 54 are all composed of an assembly shaft, an adjusting sleeve slidably assembled on the assembly shaft, an adjusting electromagnet and an adjusting spring for controlling the adjusting sleeve, a splitting and combining gear fixed on the adjusting sleeve, and a linkage gear axially fixed on the other side of the assembly shaft.

[0036] In addition, the bottom-mounted guide pump 4 and the multiple top-mounted guide pumps 5 can perform one-to-many transmission, which is realized by the lateral transmission and angle adjustment structure of the bottom-mounted guide pump 4. During implementation, in order to cooperate with the angle adjustment, a lateral flip groove 55 is opened on the outer surface of the second drive cover 51, and a flip adjustment seat 56 for installing a gear transmission group is movably installed inside the lateral flip groove 55.

[0037] In order to cooperate with lateral transmission, the gear transmission group includes: a limit gear 12 movably installed inside the second drive cover 51 through a bottom transmission shaft 11 and a movable adjustment gear 14 movably installed inside the flip adjustment seat 56 through an elastic telescopic transmission shaft 13.

[0038] The elastic telescopic transmission shaft 11 includes a lateral transmission shaft axially fixed to the movable adjustment gear 14 and an internal telescopic shaft inserted into the transmission end of the lateral transmission shaft through an extrusion spring. An opening is opened on the outside of the lateral transmission shaft, and then the telescopic adjustment of the internal telescopic shaft is controlled through the opening on the outside, thereby facilitating separation and adjustment.

[0039] In order to cooperate with the limiting and synchronous transmission, two transmission limiting through holes 15 are opened on the inner side of the lateral flip groove 55, and a synchronous shaft hole 16 is opened inside the limiting gear 12 at the position corresponding to the transmission limiting through holes 15.

[0040] When the flip adjustment seat 56 controls the elastic telescopic transmission shaft 13 and the movable adjustment gear 14 to be arranged horizontally, the movable adjustment gear 14 and the limit gear 12 are laterally meshed and transmitted, and the outer side of the elastic telescopic transmission shaft 13 is inserted into the horizontal transmission limit through hole 15, so that the angle of the flip adjustment seat 56 can be limited. At this time, the bottom transmission shaft 11 and the elastic telescopic transmission shaft 13 are arranged at 90°.

[0041] When the flip adjustment seat 56 controls the elastic telescopic transmission shaft 13 and the movable adjustment gear 14 to be arranged longitudinally, the movable adjustment gear 14 is separated from the limit gear 12, and the outer side of the elastic telescopic transmission shaft 13 is inserted into the synchronous shaft hole 16 inside the limit gear 12. At this time, the angle of the flip adjustment seat 56 can be limited. At the same time, the bottom transmission shaft 11 and the elastic telescopic transmission shaft 13 are coaxially arranged, and the movable adjustment gear 14 is coaxially linked with the limit gear 12.

[0042] Furthermore, the cable cabinet 1, the first assembly cabinet 2 and the second assembly cabinet 3 are all provided with lateral air inlets connected to the outside, and the lateral air inlets are provided with metal filters 17. Among them, a magnetically controlled closed cover plate 18 is electrically controlled on the outer surface of the metal filter 17, and a humidity sensor 19 is provided on the inner side of the metal filter 17.

[0043] During implementation, the humidity sensor 19 measures the moisture concentration of the air inlet. When the humidity of the air drawn in from the outside is very high, the magnetically controlled closed cover 18 will be automatically activated, thereby closing the lateral air inlet at that position, and at the same time, the air cooling and heat dissipation will be closed, and a liquid cooling cycle heat dissipation method will be adopted. The magnetically controlled closed cover 18 is composed of an electromagnet fixed on the outer side of the outer side of the metal filter 17, a closed cover located outside the metal filter 17, and an iron spring installed between the electromagnet and the closed cover. The iron spring is controlled to contract by activating the electromagnet, thereby pulling the closed cover to completely close the lateral air inlet.

[0044] In the specific implementation of the modular distribution network switch cabinet structure in this embodiment, the driving unit inside the bottom diversion pump 4 controls the air to be drawn in from the lower opening of the cable cabinet 1, then drawn out along the heat exchange component 7, and then discharged from the top of the switch cabinet body; when the internal temperature gradually increases, the top diversion pump 5 starts to drive the heat exchange fluid inside the heat exchange component 7 to circulate, thereby enhancing the heat exchange effect. The temperature inside different modular cabinets is monitored by automatic temperature control, and then the transmission state between the cabinet and the driving unit is controlled, thereby reducing energy consumption. In addition, the sealing of the switch cabinet can be automatically adjusted according to the changes in internal and external humidity and temperature, thereby switching different heat dissipation methods, and the self-control performance is greatly improved.
